How come Paris goes from Ensign back to Lieutenant in well under two years, but Kim has been an Ensign for over six years now?

The Queen at one point announces to a Drone "I've disconnected you from the hive mind." But in TNG "Best of Both Worlds", Crusher surmises from studying Picard that "he's part of their collective consciousness now. Cutting him off would be like asking one of us to disconnect an arm of a foot, we can't do it!" And lest we think Crusher was simply mistaken, remember that they then used this weakness to defeat the entire Borg attack.

Great Moment :

The destruction of the Delta Flyer

Body Count :

Several drones get their heads cut off. A whole bunch of people get virtually assimilated.

Plotline

When Seven begins to have dreams, it turns out she is tapping into a virtual environment which a small number of Borg drones inhabit while they are regenerating. The Borg Queen is making every effort to find and stamp out these traces of individuality, and Seven is determined to help the rebel Borg. Janeway, sensing a weakness which could destroy the whole collective, is quick to lend her own support.
